Jaycee Lee Dugard has been found. No DNA test has been done to confirm the woman's claims, but she remembers her childhood.

From ABC News:

A California stepfather who heard his little girl scream as she was abducted 18 years ago said she has been found alive and well and her captors are in custody.

A woman claiming to be Jaycee Lee Dugard, now 29, walked into a police station in tiny Antioch, Calif., Wednesday, her stepfather Carl Probyn told ABCNews.com today. Based on conversations his wife has had with police, the FBI and the woman herself, Probyn said the family is convinced Jaycee has been found.

"I had personally given up hope," he said. "I had just hoped for a recovery" and to find the people responsible.

Instead, he said, "I've actually won the lotto."

Authorities are keeping mum until a press conference at 6 p.m. ET, but court records show that a search warrant was issued Wednesday for 1554 Walnut Ave., Antioch. Records indicate it is the address of Philllip and Nancy Garrido.

Additional court records state that the Garridos are in police custody in Concord, Calif. Both are charged with kidnapping to commit rape and bail was set at $1 million.

FBI Sacramento Special Agent Steve Dupre told ABCNews.com today that he could not confirm any details about the woman, but that "we've had an open case since it happened in 1991."

The El Dorado County Sheriff's Office, which covers the area where Jaycee was taken, declined to provide further details.

Probyn said his stepdaughter had been transferred from Antioch to Concord, a smaller city in the area more than a two hour drive from the South Lake Tahoe, Calif., neighborhood where Jaycee was snatched on June 10, 1991 as she tried to catch the bus to school.

"I saw them pull her in and I tried to get her," Probyn said.

The kidnapping terrified the community and led to a massive manhunt.

His wife, Terry Probyn, who now lives in Orange County, left for northern California at 6 a.m. today, joining the couple's 19-year-old daughter who was just a year old when her sister was kidnapped.

"She's in shock," Probyn said of his wife. "I told her and my daughter to sit down there and think of questions to ask her."

Probyn said he doesn't have any details of what had happened to Jaycee for the last 18 years or who abducted her, but he claims that the FBI told his wife that "they have Jaycee and the people she was with."

"She sounds like she's okay," he said. "She had a conversation with my wife and she remembers things. I hope she's been well treated this entire 18 years."
